SYDNEY, Oct 12 (Reuters) - Australia's Qantas Airways said on Sunday that it was one of the companies whose customer data had been published by cybercriminals after it was stolen by a hacker in a July breach of a database containing the personal information of the airline's customers.
The airline said in July that more than a million customers had sensitive details such as phone numbers, birth dates or home addresses accessed in one of Australia's biggest cyber breaches in years. Another four million customers had just their name and email address taken during the hack, it said at the time.
The July breach represented Australia's most high-profile cyberattack since telecommunications giant Optus and health insurer Medibank were hit in 2022, incidents that prompted mandatory cyber resilience laws.
On Sunday, Qantas said in a statement that it was "one of a number of companies globally that has had data released by cyber criminals following the airline’s cyber incident in early July, where customer data was stolen via a third party platform".
"With the help of specialist cyber security experts, we are investigating what data was part of the release," it said.
"We have an ongoing injunction in place to prevent the stolen data being accessed, viewed, released, used, transmitted or published by anyone, including third parties," the airline added.
Hacker collective Scattered Lapsus$ Hunters is behind the Qantas data release, which occurred after a ransom deadline set by the group passed, the Guardian Australia news site reported.
Qantas declined to comment on the report.
itnews.com.au - TPG Telecom has revealed that iiNet’s order management system was breached by an unknown attacker who abused legitimate credentials to gain access.
The telco said [pdf] that it “appears” that a list of email addresses and phone numbers was extracted from the system.
“Based on current analysis, the list contained around 280,000 active iiNet email addresses and around 20,000 active iiNet landline phone numbers, plus inactive email addresses and numbers,” TPG said.
“In addition, around 10,000 iiNet usernames, street addresses and phone numbers and around 1700 modem set-up passwords, appear to have been accessed.”
The order management system is used to create and track orders for iiNet services.
TPG Telecom said that the system does not store “copies or details of identity documents, credit card or banking information.”
The telco apologised “unreservedly” for the incident and said it would contact all iiNet customers, both those impacted as well as “all non-impacted iiNet customers to confirm they have not been affected.”
Investigations so far have not uncovered any escalation of the breach by the attacker beyond the order management system.
TPG Telecom has advised relevant government agencies of the incident.
